Device Identification and Product Description

The device shown in the visuals is an advanced medical device system used in the management of Type 1 diabetes. The set consists of an insulin pump as the main unit, a transmitter (for the continuous glucose monitoring (CGM) system that sends data to this pump), a charger for this transmitter, a software upgrade kit, user manuals, and various spare parts/accessories.

Brand and Model Information

The 100% accurate brand and model information obtained as a result of detailed visual inspection and label readings is as follows:

• System/Kit Brand and Model: Medtronic MiniMed 780G
• Insulin Pump Model: MiniMed 780G (The system was confirmed to be 780G based on the inscriptions on the “Software upgrade kit” and “User Guide” in the visual.)
• Transmitter Brand and Model: Medtronic Guardian Link (3)
• Charger Model: Medtronic Charger (MMT-7715)

• 4 Clear zip-lock bags containing various accessories (Clip, adapter, etc.)
• 1 White test or calibration socket (with GL3 written on it)
• 1 Belt clip or carrying accessory (Black, piece next to the pump)

General Condition and Physical State

The physical condition of the products varies by part:

• Insulin Pump: The device appears to be used. There are noticeable abrasions, tape marks, and adhesive residues on the label on the back panel. Scuff marks resulting from general use are visible on the casing. However, the screen and keypad appear intact.
• Software Kit Box: The “It’s here! MiniMed 780G software upgrade kit” box is in its transparent protective packaging (foil) and is in new/unopened condition.
• Booklets and Other Boxes: The system user manual and reservoir box appear clean and in good condition; no tears or deformations have been detected.
• Transmitter and Charger: The Guardian Link (3) transmitter and charger are in physically sound condition. A green LED light is illuminated on the transmitter.

Label and Serial Number Information

The technical label information clearly readable in the visuals is as follows:

• Transmitter:
  • REF: MMT-7911NA
  • SN (Serial No): GT7986582N
  • FCC ID: OH27821
  • IP Rating: IP48 (Water resistance standard)
• Charger:
  • REF: MMT-7715
• Insulin Pump:
  • SN (Serial No): NG2548811H
  • Configuration No (CONF): M990175A001
• Other Codes: The code “FL12311633756” is found on the reservoir box.

Screen and Electronic Analysis

The pump’s screen is functional and displays an image. The data read on the screen is as follows:

• Screen Status: The color LCD screen is working flawlessly; no dead pixels or cracks have been observed.
• Menu/Alert: The “Reservoir & Tubing” menu is active on the screen. This indicates that the device is in the setup or part replacement phase.
• Time: The device clock shows 14:53.
• Active Insulin: The screen displays “Act. Insulin 0.0 U”.
• Graphic Data: A glucose trend graph showing the range of 100 to 350 mg/dL is visible on the screen, but the current value reading is not visible in the immediate visual.
• Transmitter Status: A green LED light is illuminated on the separate Guardian Link 3 transmitter, which proves that it is receiving power electronically and is active.

Battery Status

The entire battery icon in the upper left corner of the pump’s screen is green. This indicates that the device’s battery is full or nearly full. The Guardian Link 3 transmitter has a rechargeable structure, and since its light is on in the visual, it is understood that it has charge.

Areas of Use

This product is used for continuous monitoring (CGM) of blood sugar levels and automatic or manual delivery of the required dose of insulin to the body in individuals with Type 1 diabetes. The 780G model is a hybrid closed-loop system capable of automatic correction based on sensor data to reduce the risk of hypoglycemia and hyperglycemia.

Potential Failure Risk and Assessment

The abrasion and adhesive residues on the rear surface of the insulin pump suggest that the device has been used for a long time or secured with tape. While this is a cosmetic defect, no deep cracks affecting the structural integrity of the casing are visible. The electronic functions of the device (screen, menu navigation, sensor light) are active according to visual evidence. Mechanically, the integrity of the pump’s clip slots and battery cover should be checked. No “Error” or fault messages are visible on the screen.

Accessories and Compatibility

The “Software upgrade kit” included in the set likely contains a computer connection apparatus or a software license that enables the use of newer features by updating the pump’s software. The “MiniMed Reservoir” box is a consumable required for filling the device with insulin. All accessories are original parts compatible with the Medtronic MiniMed series.
